DoctrineORMModule zend framework 2.1.5 - exception(Model\Entity is not a valid entity or mapped super class)

Question

I know exactly same type of issue has been posted here many times. But not a single one solved my problem, really frustrated ,googling for more than 2 days finding solutions still with no success. I am stucked here not able to proceed ahead with my project. I have stated solutions I found through google in the last which didn't solve my problem.

Here are my specs: Using Zend Framework 2.1.5 with doctrineORMModule on wamp server / php 5.4.3 / apache 2.2.22.

Here are my doctrine configurations in Application/config/module.config.php

    // Doctrine Configurations
'doctrine' => array(
        'driver' => array(
                // defines an annotation driver with two paths, and names it `my_annotation_driver`
                'my_annotation_driver' => array(
                        'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
                        'cache' => 'array',
                        'paths' => array(
                                __DIR__ . '/../src/Application/Model',
                        ),
                ),

                // default metadata driver, aggregates all other drivers into a single one.
                // Override `orm_default` only if you know what you're doing
                'orm_default' => array(
                        'drivers' => array(
                                // register `my_annotation_driver` for any entity under namespace `My\Namespace`
                                'Application\Model' => 'my_annotation_driver'
                        )
                )
        )
),
// End doctrine configurations

User Entity class in Application/src/Application/Model/User.php

    return $this->username;
}
}

UserController in Application/src/Application/Controller/UserController.php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

class UserController extends AbstractActionController
{
public function IndexAction()
{
    $em = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');

    $user = $em->find('Application\Model\User', 1);
    var_dump($user);

    exit;
}
}

Solutions I found:

• turning off eaccelerator (eaccelrator is not installed on my wamp server, So this is not an issue)
• change annotation mapping @Entity to @ORM\\Entity (checked using both ,didn't solve my problem- seems like $config->newDefaultAnnotationDriver($path, true) second param simpleannotationreader is set to true.So it will read simple annotation ex. @Entity though I checked by using @ORM\\Entity still doesn't work)
• Some Place I found that I should call annotationRegistry::somemethod() if this is the solution then which method I shud call from annotationRegistry class and where's the exact place to call.

cmd commands:

• ./vendor/bin/doctrine-module orm:validate-schema shows no error '[Mapping] OK - The mapping files are correct. [Database] OK - The database schema is sync with the mapping files.'
• however executing this command - `./vendor/bin/doctrine-module orm:info throws exception as follows 'You do not have any mapped orm entities according to the current configuration. I you have entities or mapping files you should check your mapping configuration for errors.'

That's it .Now all I can do is keep my hope and patience. thanks for checking out my issue.

Answer 1

I found what was your problem: invalid comments. To describe Doctrine 2 ORM Entities you should annotations:

So for example - instead of:

/*
 * @Id 
 * @Column(type="integer")
 * @GeneratedValue(strategy="AUTO")
 */
private $id;

you should use:

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

As mentioned before - you should use annotations from Doctrine 2 ORM as follow (with @ORM\\ at the beginning):

/**
 * @ORM\Column(type="string", length=31)
 */
private $username;

I encourage you to use following rule: all Entities store in subdirectory Entity, and functions operating on that entity - in subdirectory Model ( getUsers(), getUser(id), etc ).

Complete User Entity class in User/src/User/Entity/User.php (in my case):

namespace User\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Users table
 *
 * @ORM\Entity
 * @ORM\Table(name="users")
 * @property int $id
 * @property string $username
 * @property string $password
 * @property string $email
 */
class User
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=31)
     */
    private $username;

    /**
     * @ORM\Column(type="string", length=32)
     */
    private $password;

    /**
     * @ORM\Column(type="string", length=63)
     */
    private $email;

    /**
     * @ORM\Column(type="string", length=63)
     */
    private $name;

    /**
     * @ORM\Column(type="string", length=127)
     */
    private $profile_pic;

    /**
     * @ORM\Column(type="string", length=127)
     */
    private $cover_pic;

    /**
     * @ORM\Column(type="integer")
     */
    private $status;

    /**
     * @ORM\Column(type="datetime")
     */
    private $created_at;


    public function __construct() {
    }


    /**
     * Magic getter to expose protected properties.
     *
     * @param string $property
     * @return mixed
     */
    public function __get($property)
    {
        return $this->$property;
    }

    /**
     * Magic setter to save protected properties.
     *
     * @param string $property
     * @param mixed $value
     */
    public function __set($property, $value)
    {
        $this->$property = $value;
        return $this;
    }
}

I also use plural form when I want to call some table.

Eg users , articles , posts

And singular form for the Entity name (single record)

Eg User , Article , Post

But this is just one of the patterns I am using.

BTW. Thanks for info about some usage of Doctrine 2 ORM console tool. I have never used ./doctrine-module orm:info , but only ./doctrine-module orm:schema-tool:create --dump-sql > database.sql

Answer 2

Your problem is related to Docblock annotation "starter" characters:

A Docblock annotation is a C++ style comment starting with slash (/) and two asterisks (*) . This "starter" characters are required, otherwise Doctrine won't recognize the annotation .

Change all comments to start with a /** and it will work.
